After reading all the other threads, the last two PA systems that come in my mind are the Hisonic HS321 vs. AmpliVox SW222. What are the pros and cons when compared to each other?

Don't know the pros and cons, but don't buy the Hisonic. I have one, and it's junk. It's now a back-up unit. I'm using a Mipro system.

I love my Hisonic. It's a smaller model than the one you show here, but my little one works wonders for me in shows with 100 people or less. For anything bigger, I use my Fender PD150. No offense intended to Jim, perhaps he got a dud, but in my experience, Hisonic has worked great for me and is worth considering.
